Aleksandra Duliba wins the 2013 L.A. Marathon

The 27-year-old from Belarus claims a victory in her professional debut and collects a $50,000 gender bonus for finishing ahead of men's winner Erick Mose of Kenya.

9:35 a.m.: Aleksandra Duliba of Belarus has won the women’s race and $50,000 gender challenge in the 28th Asics Los Angeles Marathon, outrunning Ethiopia’s Zemzem Ahmed to win the race in her first marathon in an unofficial time of 2:26:08, a Belarus national record.

Kenyan Erick Mose has won the men’s race, after outkicking countryman Julius Keter in the 24th mile. Mose won in an unofficial time of 2:09:43. The marathon record stands in 2:08:24. Keter finished second while Nicholas Chelimo, also of Kenya, was third in 2:10:41. Cal State Fullerton product Nick Arciniaga finished seventh in 2:17:04.

Ahmed finished second in the women's race in 2:30:33. Agoura Hills' Deena Kastor, 40, finished third in 2:32:38.

9:32 a.m.: First-time marathon runner Aleksandra Duliba, a 27-year-old from Belarus, and Kenyan Erick Mose are nearing victories in the women’s and men’s races of the L.A. Marathon. Mose, in Mile 25, has stretched his lead over countryman Julius Keter, while Duliba, now running on Ocean Avenue in Santa Monica, is nearing the $50,000 gender challenge bonus, shrugging off a right hamstring twitch at the 24.5 mile.

9:28 a.m.: In Mile 24, Aleksandra Duliba continues to push for a $75,000 pot of gold at the end of the L.A. Marathon by maintaining not only her substantial lead over her nearest female pursuer, but on men’s runners Erick Mose and Julius Keter for the race’s $50,000 gender challenge.

Mose and Keter would have to substantially quicken their pace, unlikely at this late-going point. Duliba caused some alarms at the 24.5-mile mark, slightly grabbing her right hamstring and grimacing before returning to form.

9:20 a.m.: The L.A. Marathon men’s race has become a two-man contest in Mile 22 between Kenya’s Erick Mose and Julius Keter. Keter, 24, won the 2008 Baltimore Marathon in 2:11:56. Currently, the L.A. Marathon men’s winner is on pace to win in 2:10:07. Keter has won the Hispaniola Lowenbrau Half Marathon in the Dominican Republic four consecutive times. Mose holds citizenship in Kenya, but was born in Toluca, Mexico.

The men are running hard, trying to catch women’s leader Aleksandra Duliba for the $50,000 gender challenge bonus. Mose holds a slight lead over Keter, who marathon officials say is the grandson of legendary Kenyan distance runner Kip Keino, at the moment. Race officials put the men's duo at about one minute behind Duliba.

9:15 a.m.: In the 22nd mile, Alexsandra Duliba is on pace to win the L.A. Marathon by about a quarter of a mile, marathon officials announced. Duliba is on pace to finish in 2 hours 27 minutes 14 seconds while the men’s estimated winning time would be 2:09:52, which would give Duliba the $50,000 gender challenge bonus.

A pack of five now lead the men's race, headed by Erick Mose and Julius Keter, while defending champion Simon Njoroge and early leader Philemon Baaru have now slipped off the lead pace in Mile 21.

9:08 a.m.: While Aleksandra Duliba continues to maintain a strong lead in the L.A. Marathon women’s race, the men’s competition has become a six-man chase in Mile 20 with Kenya’s Erick Mose, Philemon Baaru and Weldon Kirui in the front of the group.

Duliba has a quarter-mile lead over the men in the $50,000 bonus gender challenge in Mile 21, but marathon experts are intrigued with how the first-time marathon runner can hold up in the uncharted waters as the grind of the race takes full effect. Duliba is calmly checking her stopwatch as she makes her way toward the finish line at the Santa Monica pier.

9:00 a.m.: Aleksandra Duliba of Belarus is making her first marathon a stirring one, expanding her lead in Mile 19 over Ethipia’s Zemzem Ahmed in the Asics L.A. Marathon while holding a lead over a pack of eight men’s leaders for the $50,000 gender challenge.

Duliba has been spotted frequently checking her stopwatch to monitor her split times. The 27-year-old is pulling away from the more experienced Ahmed.

8:56 a.m.: Kenya’s Nicholas Chelimo and Philemon Baaru are the leaders of the men’s race in the L.A. Marathon at Mile 17, in front of a group whose time is now closing the gap on women’s leaders Aleksandra Duliba and Zemzem Ahmed, who are on pace to finish in 2:28:08. Duliba, 27, has extended her lead to 8.5 seconds in Mile 19, and is looking very strong.

8:47 a.m.: American Deena Kastor, 40, fell off the pace of the lead in the women’s race of the Asics L.A. Marathon, but she has moved back into third -- podium position -- as Belarus’ Aleksandra Duliba and Ethiopia’s Zemzem Ahmed continue to lead the race.

Krige Schabort just claimed $3,500 by winning the elite wheelchair race in 1:30:50, a new course record in his fourth consecutive L.A. Marathon victory.
